The Transfer of Biomass in Food Chains: Efficiency and Energy Loss

The video discusses biomass and energy transfer in food chains, highlighting inefficiencies at each trophic level. It explains the pyramid of biomass, calculates transfer efficiencies, and explores energy loss due to non-ingestion, non-absorption, and respiration. The video emphasizes the impact of trophic levels on efficiency, showing that fewer levels increase efficiency and support more organisms.

What are the three trophic levels mentioned in the food chain example?

How much biomass do zebras gain after consuming 700 kilograms of grass?

What is the efficiency of biomass transfer from grass to zebra?

List the reasons why biomass transfer is inefficient between trophic levels.

What percentage of biomass is transferred from zebras to lions?

Explain how energy is lost during the transfer from one trophic level to another.

What role do producers play in a food chain?

How does the efficiency of energy transfer affect the number of trophic levels in a food chain?

What is the biomass efficiency from corn to humans in the given food chain example?

Describe the impact of decreasing the number of trophic levels on food chain efficiency.
